1. What is constructor overloading in C++? A. Using multiple constructors with the same name but different parameters B. Creating a constructor that returns a value C. Using constructors to initialize static
In addition to overloading constructors with different parameters, we can overload constructors with default parameter values, as well. For example: class Circle {private:double radius;public:Circle() {radius = 1.0;}Circle(double r) {radius = r;}Circle(double r, double x, double y) {radi...
If you’re coming from a language such as Java or C#, the concept of constructor overloading is a pretty common one. But as a refresher in say C#, we can overload constructors like so : classMyClass{publicMyClass(string value){this.value=value;}publicMyClass(int value){this.value=va...
// overloading class constructors #include <iostream.h> Class CRectangle { int width, height; public: CRectangle (); CRectangle (int,int); int area (void) {return (width*height);} }; CRectangle::CRectangle () { width = 5; height = 5; } CRectangle::CRectangle (int a, int b)...
Constructor Overloading in C++ In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments.This concept is known as Constructor Overloading and is quite similar to function overloading. ...

Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g.Vectorclass has 4 types of constructors. If you do not want to specify the initial capacity and capacity incremen...
